In 1995, postdoc indicator information was collected in a substantially different way than in 1993, 1997, and 1999. In 1995,
the information was collected in a special, one-time only section of the survey that focused on other work related
information. In the other years, postdoc information was obtained in the section of the survey that focused on the current
job of the respondent. Consequently, postdoc information from 1995 may not be directly comparable to information
collected in the other years.
For 1995, see B_JOB_PRINCIPAL_JOB_POSTDOC

This variable is derived from other variables within SESTAT. More information is available on the derived B_JOB_POSTDOC_APPT_IND page
